My 2000 7.3 diesel truck began acting up while driving through large, not deep water puddles in a drive day on a rainy day. Has 170,000 miles on it.
The water in fuel light, wait to start light, and service engine light came on, the truck stalled. Had to drain fuel seperator, would barely keep running, except at idle runs smooth, so hauled it home. These three lights flicker on, the engine stalls for a split second, then typically restarts(is a standard shift-?self pop-starting). Seems to act up when I hit the slightess bump or shift gears. I just drained the fuel tank and changed the fuel filter tonight, then added fressh fuel and KLEEN fuel stabilizer, ANY OTHER SUGGESTIONS? I have never had any problems with the truck or the feul system. Would this likely be a computer problem or water in fuel sensor issue since stalls engine and triggers other lights? Is this sensor located in the filter canister?

i am having the same problem with my 99, t even stalled when i slammed the door shut once or twice. the same 3 lights are flashing and going crazy when it stalls. what do you guys think. something wrong w the IDM and PCM fuse under dash? or the # 32 relay under hood?
thanks

I have no chip, I tried a TS chip shortly after that, but it would not allow the engine to start, so I sent it back. I only wanted to get a little better fuel economy they said it would give me.
My problem seems to have been water in the feul system, I pumped the tank empty, changed the feul filter, ran KLEEN through the first tank full and have not had furhter problems. I have put about 5,000 miles on it since then, always pulling livestock trailer.
Good point on the chip, I would also suggest making sure your computer is plugged in snuggly if have unplugged it in the past.

no do not have a chip in the truck. just started acting up one warm day and now will not go away. will be checking into the PCM connection tomorrow. any other ideas? those three lights blink and flicker in sync. you can hear it going nuts.

batteries test out good with the load tester. have a snap-on ethos scanner and it was not pulling up any new codes that were not there before way back 6 months ago. checked every fuse in both boxes. going to pull the boxes out of truck and check connections did have an issue with wiper motor contact spade in the box loosing contact etc. but looking for any other things. went over all the connections and wiggled everything while it was runing to duplicate the stalling etc with no luck. PCM short?

ok have some news. have a 2001 ford pcm and was going to swap it but when we pulled the 99 pcm out we found a "superchip" in the board. there is a number on the back of the chip and it is gold in color. we removed it and the symptoms seemed to of gone away testing it more tomorrow. any ideas what the chip is. does the pcm need to be reflashed back to stock or by removing it it goes to stock. long story short. bought truck a year ago from guy in florida with blown motor and finding out more and more what was lied about with the truck which was not chipped.
